Abstract: 346,617. Lathes. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitestrasse, D³sseldorf, Germany. June 14, 1930, No. 18290. Convention date, June 15, 1929. [Class 83 (iii).] In a screw-cutting device particularly for cutting taper threads on the ends of tubes the rotating work is threaded by a tool 5 mounted on a compound slide rest controlled by a lever arm 3 which carries a nut-segment 2 engageable with the lead screw 4 and which is also connected through bearing-member 18 to the transverse upper member 6 of the slide rest. The lever arm is slidably and rotatably mounted on a shaft 7 which is angularly adjustable in a plane parallel to the work axis in accordance with the required taper. The nutsegment 2 is slidably mounted on the lever arm in order to allow for the angularity of the shaft 7. A member 8 is secured to a non-rotating screw 9 which is slidable in the longitudinal slide 1 and coacts with a feed-nut 17 rotatably mounted in the cross slide so that when the nut-segment 2 is engaged with the lead screw, the member 18 causes the tool to be brought up to the work. At the end of the traverse a stop 10 acts through inclined surfaces 11 to disengage the nut-segment from the lead screw, and to withdraw the cross slide, the longitudinal slide being then returned by a weight 12. The automatic depth feed of the tool is effected by a stop 14 which after each operation engages a lever 13 to actuate a ratchet wheel 16 connected to the feed-nut 17. The lever 3 may be raised to engage the nut-segment with the lead screw by means of a handle 19 connected through gearing, Fig. 1, with a slide 18.

Title: Improvements in and relating to tractor trailer road vehicle couplings
IPC: B60D1/44
Filed: 1945-07-18
Abstract: 596,090. Tractor-trailer couplings. RIVERS, T. H. July 18, 1945, No. 18406. [Class 103 (v)] Fig. 1 shows in sectional elevation a trailer head 1 with pivoted jaws 14, 15 locked over an arc-shaped draw-bar 28 shown in plan, Fig. 5, as carried by tractor 25; the jaws 14, 15 grip a sleeve 31, which carries rollers 32 moving in a channel in the rear face of the draw-bar 28 and is borne by a radius rod 29 swinging about a vertical pivot 30 mounted on the tractor. The trailer head 1 is secured to spindles 3 rotatably and slidably mounted in bearing members 4 forming part of or secured to a caravan or other trailer vehicle. When the tractor turns relatively to the longitudinal axis of the trailer the jaws 14, 15 and sleeve 31 move away from the middle of the draw-bar to a position where the line of the tractor pull is in line with the tractor arms. Stops 34 at each end of the draw-bar 28 operate means for setting the casing 10, which carries the jaws 14. 15, free to turn about the vertical bevond the limits afforded by the draw-bar. The casing 10 is normally locked with respect to the post 7 fixed in the head; the locking means, shown in plan Fig. 2, comprise a cam plate 8, secured to the post 7 and releasable plungers 18, mounted in the casing 10, engaging cams on the plate 8. Outward radial movement of either plunger, which would result in release of the lock, is normally prevented by a projection 21 of a bell-crank lever pivoted at 23a, 23b; when the arm 24 of the bell-crank is pressed against a stop 34 of the draw-bar the projection 21 is withdrawn and the torque between the casing 10 and cam plate 8 as the tractor turns beyond the limit of the draw-bar forces a locking- plunger 18 radially outwards. The casing 10 is made rotatable by being carried on rollers 11 engaging its upper and lower faces.

Abstract: 698,883. Toothed gearing. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1951 [July 24, 1950], No. 18486/50. Class 80 (i). [Also in Group XXXI] A steering gear of the rack and pinion type comprises a rack 11 mounted in a carrier 8 through which motion is transmitted to the steering mechanism for the wheel or wheels, the required resilient pressure being produced by a spring pressed pawl 10 in the form of a yoke which straddles the carrier and engages the rack, the pawl having an 'internal cylindrical surface loosely embracing the carrier and an external cylindrical surface the axis of curvature of which is perpendicular to that of the internal surface, the arrangement permitting the rack to rock to some extent within the pawl and the latter to rock to some extent about the axis of curvature of its external surface. The rack 11 is of D-shape in cross section and is mounted between abutments in the carrier 8 so that it has no independent longitudinal movement. The pawl engages a cut-away portion of the casing 1 which houses the rack and carrier so that it cannot move longitudinally with the rack. The ends of the carrier are joined by links to half-track rods which in turn operate steering arms. The half-track rods are hollow to act as oil reservoirs for the joints. Concertina type closures between the ends of the carrier and the casing 1 exclude dirt from the rack and pinion.

Title: Method of manufacturing exhaust mufflers
IPC: F01N13/18
Filed: 1961-05-24
Abstract: <PICT:0936536/III/1> <PICT:0936536/III/2> <PICT:0936536/III/3> Mufflers used for reducing noises of exhaust in internal combustion engines are given a protective ceramic coating by immersing the muffler in a suspension of pulverulent fusible corrosion-proof ceramic material in form of a slurry, draining excess slurry from the muffler, drying and firing.  The mufflers which have elongated bodies and contain partitions or baffles and sections of pipes which may be perforated or louvred, are provided with temporary apertures in the upper and lower end walls of the p  body, e.g. 39 and 40, Fig. V, to allow the slurry to pass through the interior and to allow the escape of air.  During passage through the dipping tank the muffler is rotated whilst held in a nearly upright position so that the upper aperture reaches the uppermost point of the interior of the muffler during rotation. When draining the muffler is held at an acute angle so that the lower aperture is substantially at the lowest point of the interior of the muffler.  The mufflers are hooked to a yoke, Fig. II, connected to a friction wheel 19 rotatably mounted in carrier 3 travelling on a conveyer.  When the carrier is positioned over the slurry tank 15, the friction wheel engages a metal strip 18 which causes the wheel 19 and the supported muffler to rotate as it passes through the slurry.  The muffler assumes various angles as it rotates in the slurry which allows those parts which surround air pockets such as 45, Fig. V, caused by the interior transverse partitioning, to contact the slurry.  On withdrawal from the slurry the muffler is drained by holding it in a slightly inclined position as it returns along the conveyer by a link 46, Fig. VII, having hooks attached to both the carrier and the muffler.  The drained muffler is dried by blowing warm air through the interior in the apparatus indicated in Fig. VIII (not shown) which comprises a manifold and a series of conduits which connect to the mufflers.  The ceramic coating is then fused in a furnace. Before the slurry application the metal surface of the muffler may be heated to a high temperature and dipped in a succession of alkali-water-acid-water tanks using the same apparatus as described above for this pickling process.  The cross partitions or baffles in the muffler interior are vented at points along their junctions with the muffler casings which are lowermost or uppermost when the muffler is held at an angle to the vertical. Suitable venting apertures are shown at 41, 42, 43 and 44, Fig. V. To facilitate drainage small holes may be drilled adjacent the muffler edge which are small enough to be sealed by the fused ceramic coating.
